By now, you’ve probably seen it, or at least heard about it — the highly controversial 30-second TV spot put out by the Wendy Davis campaign. Known as the “wheelchair ad,” the spot draws immediate attention to the fact that Texas Attorney General and GOP gubernatorial candidate Greg Abbott has to use a wheelchair to get around…having been severely injured years ago in a freak accident.

After blistering bipartisan criticism of the ad from politicians as well as pundits, Democrat Wendy Davis didn’t apologize or back down. Instead, she doubled down, as Fox News reports:

Davis dug in Monday in the face of heavy criticism, claiming at a Fort Worth news conference that the ad was designed to portray Abbott as someone who worked against the disabled. During her remarks, Davis was flanked by disability rights activists, including two people in wheelchairs.
